/ RAILWAY-TRUCK JACK.

SPECIFICATION forming part of Letters Patent No. 446,378, dated February10, 1891..

Application i'iled October 10,1890. Serial No. 367,732 (No model.)

To @ZZ whom, it may concern.-

Be it known that I, .I OHN C. CARBINE, a citizen of the United States ofAmerica, and a resident of Atlanta, in the county of Fulton and State ofGeorgia, have invented certain. new and useful Improvements inRailway-Truck Jacks; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesaine, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part of this specification.

This invention relates to jacks, and more particularly to the properconstruction of such a device of this class as would be particularlyadaptable to use in the process of removing the bearing-brasses from thetrucks of railway-cars, furnishing, however, incidentally a jack whichis applicable for general service where hoisting is desired through asmall range of distance, the invention consist- -ing in certain detailsand novel arrangement thereof, all of which will be hereinafter fullydescribed, and the parts claimed as new will be specifically pointed outin the claim.'

In the accompanying drawings, Figure I is a side elevation of a portionof the car-truck, showing my device attached. Fig. 2 is an edge View ofthe wheel, showing the greasebox, and the present invention in sideeleva.- tion.

In the figures, like reference-marks indicating corresponding parts inthe several views, A is the wheel, and B the grease-box, both of whichare of the construction ordinarily found in railway-car trucks. Thegrapple C is so formed on its end as to hook over the liange of thewheel A,while its body rests on the corner of the tire or tread of thewheel, its free end being bifurcated and carrying between the 'endsthereof the swivelnut. CZ, through which passes the screw D, which hasswiveled to its lower end a crossbar E, and has means for the engagementof a Spanner or other wrench. cross-bar E are provided with means fol`the engagement or attachment of the chain or stirrup F, which eneirclesthe box B. Either .the chain or stirrup may be employed; but the chainis preferred by reason of its dexibility and ease of adjustment as tolength.

The operation of this device is as follows: The hook C is suitablyengaged with the wheel while the chain F is passed around the box, andthe screw D is revolved in the proper direction and will draw thecross-bar E toward the end of the grapple C, which will oloviously notonly raise the'box B, but will hold the wheel down on the track, whichlatter is not the case when an ordinary screw-jack is employed in theoperation.

I claimi In a device of the described class, the combination of thegrapple C,provided with a bifurcated end, the nut d, carried betweensaid bifurcated ends, the screwD, passing through the said nut d, thecross-bar E, swiveled to the lower end of the said screw,`and the chainF, attached to the said cross-bar, substantially as and for the purposespecified.

In testimony whereof I hereunto aflix my signature in presence of twowitnesses.
